Inventor: BUTT THOMAS
IPC: B25J19/00
Filed: 1995-06-02
Abstract: A compliance device for robot assemblies is provided which permits the automation of tooling operations that generate significant reaction loads, such as automatic riveting and the like. The compliance device includes a compliance control assembly and a tool isolation assembly. The compliance control assembly is an air cylinder having a tubular piston rod. An elongated shaft extends through the tubular piston rod and an axial bore in the piston of the air cylinder. The shaft is affixed to an end plate of the cylinder and includes a position locator cone affixed to its free end. The position locator cone is housed in the tool isolation assembly which is a cylindrical housing having a tool support end and a positionlocator end. Equally spaced-apart, radially-oriented rollers are affixed to an inside surface of the locator end of the tool isolation assembly. The rollers cooperatewith detent grooves formed in a top surface of the position locator cone to locate the tool isolation assembly in a predetermined home position when air pressure is injected into the compliance control assembly and the tubular piston rod is extended to force the rollers into the detent grooves. Air is exhausted from thecompliance control assembly during tool operations so that the tool isolation assembly is free to move in response to reaction loads created by the tool operation. The advantage of the compliance device is that it provides a robust compliance device that reliably returns to a precise predefined home position and permits the automation of heavy tool operations such as riveting.

Patent CA-2156146-A1 (CA)
Inventor: CANNEY WILLIAM MATTHEW
IPC: F25J3/04
Filed: 1995-08-15
Abstract: A cryogenic air separation process generates both an intermediate product and an output product.  The intermediate product is produced earlier in time than the output product and variations in output product measurements correlate to earlier variations in intermediate product measurements.  The process responds to plural independent variable phenomena.  The apparatus includes analyzers for providing measures of the intermediate and output products and the independent variable phenomena.  A control processor predicts a measure of the intermediate product, based on the independent variable phenomena and output predicted values therefor.  A difference is then determined between the current predicted value for the intermediate product and a measure of the intermediate product, to arrive at a prediction error.  The processor is responsive to this intermediate product prediction error to further predict both current and future values of the output product so as to enable control actions to be taken with respect to the output product to control impurities therein.

Inventor: STEWART FRANCIS
IPC: C12N15/09
Filed: 1994-06-28
Abstract: An invention is described that permits the regulation of recombination in cells, organisms or appropriate cell-free systems. The invention involves creating fusion proteins between recombinase proteins, or components of recombinase systems, and ligand binding domains derived from nuclear receptors. The fusion proteins show little recombinase activity in the absence of the ligand that binds to the ligand binding domain. Upon binding of the ligand, recombinase activity is induced. The invention provides a practical means to regulate recobination in cells and organisms and, by linking ligand binding to recombination, provides a simple means whereby ligand binding can be measured as recombination achieved.

Patent CA-2172562-A1 (CA)
Title: Apparatus and method for furnace combustion control
Inventor: EVENS LANCE J
IPC: F24H9/00
Filed: 1996-03-25
Abstract: Furnace combustion in a multi-stage or variable input furnace is controlled by operating the furnace in a high fire mode at furnace start-up until the temperature of the products of combustion, or a temperature corresponding to theproducts of combustion, equals or exceeds a selected temperature. A temperature sensor, preferably a thermostat, is located downstream of the furnace zone of combustion (e.g., in a flue collector box at an outlet from the heat exchanger).The thermostat provides an indication of the products of combustion temperature and has a set point corresponding to the selected temperature. When the productsof combustion temperature is less than the selected temperature, the thermostat contacts remain closed. The furnace is operated in the high fire mode while the thermostat contacts remain closed in response to a demand for heating, irrespective of whether the demand is for first stage or second stage heating. When the selected temperature is reached, the thermostat contacts open, thereby allowing the furnace to be operated in either the high fire or in a low fire mode, depending on the level of demand for heating, as indicated by an external room thermostat. By operating the furnace in the high fire mode until the products ofcombustion temperature reaches a selected temperature (i.e., during cold start-up operation) condensate formation is reduced and room comfort is enhanced by inhibiting air from being supplied to the room at less than a desirable temperature.
